Make your own spin art device using an old record player! Notice patterns and effects the spinning movement has on your work. When finished, post your work to the Spin Art Gallery!

Capture soap bubble patterns on paper! In this activity, learners can create beautiful pictures from popping soap bubbles.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners use an origami template to design eight amino acids. Learners configure the amino acids to form a protein. Use this activity to introduce proteins and amino acids.

In this activity, learners create models of bugs. Learners use household materials like plastic cups and straws to create models of bugs like centipedes and spiders.

In this craft-based activity, learners make DNA sequence bracelets that carry the code of an organism such as a human, trout, chimpanzee or butterfly.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

In this activity, learners explore sound by constructing an instrument toy that buzzes when you swing it.

Learners assemble a figure from a nylon stocking or sock stuffed with soil and seeds. The ends of the nylons inside the jar absorb water, which feeds the grass seeds.

In this activity on page 11 of the PDF, learners use candle wax to make "invisible" designs that are revealed with watercolor paints.

Design and create an optical illusion toy that makes two pictures appear to become one. This is called a thaumatrope and will allow the learner to investigate the phenomenon of persistence of vision.

In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.

In this activity, learners observe, explore and investigate vibrating instruments in everyday places and create music in unique ways.

In this activity, learners create three-dimensional shapes by making some origami models of simple boxes and containers.

In this activity, learners explore the gait of horses by constructing flipbooks with British photographer Eadweard Muybridge's famous photographs.

In this activity on page 11 of the PDF, learners follow simple steps to recycle old newspaper into new paper.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

Ivy Rutzky, a scientific assistant at the American Museum of Natural History, introduces an activity where learners create a scientific illustration of a monarch butterfly.

In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.
